abstract：:Oxidative stress plays a role in the pathogenesis of neurodegeneration in diabetic retinopathy (DR). However, whether an excellent reactive oxygen species scavenger, U83836E, inhibits the neurodegeneration in DR remains uncertain. This study is aimed at clarifying the effects of U83836E on DR. Two weeks after streptoz...
